Filed Dec. 16, 1927 Patented Sept. 30, A193()` UNITED STATES' PATENT OFFICE WALTHEB GosMANN, or Dommelen, GERMANY HAND FIRE EXTINGUISEER Application led December 16, 1927, Serial No. 240,526,and in Germany October 1, 1927.

The present invention relates to a hand lire extinguisher ofthe type having a container for an extinguishing fluidy underl pressure and specifically relates" to an improvement L therein involving the provision of a frangible nozzle whereby the extinguishing. fluid is released when the glass' nozzle communi-- eating with the delivery pipe is d emolished.`

It is a further object of the invention to lo provide a specic mounting for the frangible nozzle so that after use it can be readily replaced for re-use.

In addition,7 the cover4 of the tank containing the extinguishing agent is provided l5 with a filling stopper in .which is tted a e ball valve serving as 'a check valve when putting the tank under pressure. After this has been effected, the threadedbranch of thevalvejcasing for connecting thereto the air -pump is closed by a screw cap so as to provide against -any possible leakage of air Vpast the check valve. The' apparatus provided by this invention is shown in the accompanymg drawing-by Way of example. ig; 1 is a vertical section, and

Fig. 2 is a plan view of the discharge nozy zle on an enlarged scale, y r

The tank a is filled with the extinguishing agent b through the a erture provided in the filling stop er c, the eight to which it can be lled belng limited b the tube d which is rmly secured tothe c eck valve casing-Eef..

I Q. The filling sto per c is then screwed down air-tight, and t e glass tube f fitted air-tight into the branch ofthe nozzle j by eans of a metal tube g into which said gl ss tube is tightly fitted. -The nozzle j is, in turn, screwed into vthe -cover 7c. The metal tube' m g is provided with tW'o windows -oii si ht openin s h-h disposed'oppos'iteone anot er throu reuse thereof.

v "which the fire-extinguishing. fluid Vmay. e observed as longas a normal or\ whether or not there is suflicient .pressure in the tank to .eiect spraying of the fluid.-

What I claim as new and patentable is 1. A hand fire extinguisher comprising a containerfor an extinguishing Huid under pressure, and a closurefor the container, a. tube within the container for the delivery of the iluid, a nozzleupon the closure supporting the tube at its delivery end and inc uding a frangible, and transparentl 4closed tube upon the nozzle' in communication with the said nozzle and tube, and a metal tube enclosing a portion ofl therangible tube and having a sight openingtherein whereby the presence of the extinguishin iuid, under pressure, may be observed, sai frangible and transparent closed tube being replaceable after' use of the extinguisher fortlreuse thereof.

2. A hand ire extinguisher comprising'a container for an extinguishing fluid under pressure,` and a closure lfor the container, a

tube within the container for the delivery of the iiuid, a nozzle upon the closure support-Y ing the tube at its delive end, a frangible,

" `and transparent closed tu e upon the nozzle 1n communication with" the said nozzle and tube, afllling tube' mounted at its u per end in the said closure and depending th distance to determine the height to which the container may be filled with the extinguishing fluid, a valve casing to which the said end of the tube is connected, a check valve in" said casing, and a closure cap removably fitted' onto said casing, whereby, y

upon its removal,.'the extinguishing fluid erein a maybe supplied to the container, said frangi- Able and .transparent closed tube being replaceable after 4 use of the extinguisher for In testimony whereof I aiiix my signature.
